Answerman - How Does A New Distributor Get Permission To Reuse Old Dubs?
Read this - unless there is something very stupid going on Viz has got the rights to the old dub. Look how many titles from the 80's that Discotek has put out that have reused the old dub from that era like Wizard of Oz etc.
The simple fact is Viz choose not to do so because they have just spent a lot of money making their own dub - they want to recoup their investment.
Look at the recent Nozomi Kickstarter for Emma -
Let's Dub Emma A Victorian Romance Anime TV Series Season 1. They wanted $100,000 + just for a 12 episode show. Goodness knows how much Viz is spending re-dubbing 200 episodes.
They won't want to confuse the market by having *2* dubs on the market.
And again it still rolls back to - do the masters still exist for the old dub ? If we take the treatment Cyborg 009 has had they are probably in a pretty sorry state - how much work would it cost to do a decent upscale / restoration to make for a proper blu-ray release in 2018 ? Would they want to spend that money ON TOP of what they have already spent on remaking their own dub.
(Let's be realistic - to recut the dub from original Japanese masters with all the cuts / hacking DIC did, up convert it to HD etc for the probable market it would be prohibitively expensive - the only option would be to take original DIC masters and then process them but do we know 100% that the original DIC masters have been preserved well to the extent they could 20 years down the line be in a fit state for being up converted with no corruption etc )
If you definitely believe there is a market for it - go make a change.org petition and get the 20,000 / 30,000 signatures - if you can do that you might be able to make a case to Viz to spend the time / money on doing a release...till then all available evidence says it ain't happening
